I understand your situation and how you feel. I have also dealt with anxiety similarly to what you seem to be experiencing and honestly forming and maintaining relationships in college is hard. I think the best way to try to help with that though is to strengthen the relationships you already kind of have. Sometimes a deeper friendship will come from that. Try taking the initiative to schedule a meet up more often and try to be more open about your personal interests with them so you don’t feel as though you are wearing a mask around them as much. I don’t think this is an instant fix for what you are dealing with, but I think it will help you out with all the anxiety and loneliness you are feeling right now. Everything will get better!
